Used for heating, ventilation and airconditioning. The actuators serve to control the room temperature and can, for instance, be used with conventional radiators, radiators with integrated distributor, distributors/collectors for surface heating, radiant ceiling panels, chilled ceiling systems and induction air systems in combination with two point room thermostats. Further applications in bivalent heating installations.

For zone and room temperature control.

With First-Open function and stroke index. Simple plug-in connection with valve adapter. Actuators can be installed in any position.

Due to their construction, the electrothermal actuators are secured against overvoltage which could occur when switching on neon tubes. A varistor is thus not necessary.
